Which formula uses mixed cell referencing? a. $c$1+$d$1 b. $c1+$d1 c. c1+d$1$ d. c1+d1

The correct answer is (B) $C1+$D1. Please see the explanation below:

Mixed cell referencing means when we create an excel formula such that on copy pasting the formula to another cell, either row number OR column name of the cell being referred to is not changed.

By adding a $ symbol before the column name or row number, you make it constant (or absolute) and it is not automatically adjusted if copied across cells. A mixed cell reference would have a $ symbol before either the column name or the row number, as is the case in option (B). So the formula in the option will always refer to column C and column D if you paste it across cells, only the row number reference will change

Further, in option (A) $C$1+$D$1, rows and columns of both C1 and D1 are absolutely referenced. In option (C) C1+D$1$, rows and columns of C1 are relatively referenced, and of D1 are absolutely reference. In option (D) C1+D1, rows and columns of both C1 and D1 are relatively referenced. Only in option (B) the columns are absolutely referenced and the rows are relatively referenced.

okay, so i know we just goofed around in that chat, but ive been like genuinly depressed, like medically depressed for almost 4 years now. i had my first panic attack when i was 8. i woke my mum up and told her i felt like i was in a dream. like i was a goldfish in a bowl, looking at all these things going on around me and feeling . tiny. wort hless. and i now am now 17 y/o. i still feel those emotions daily. life used to go by so quick.like every day i would wake up and just like want to go back to bed cause i always felt like i was in the wrong place. i guess looking back, i was in the wrong state of mind. i took a expensive like nice trip to whyoming with my grandfather and ha ted it. like idk why. i would have loved it now, but i found myself writing in a journal everyday because i would forget what happened the day before, couldnt remember what i ate for like the previous meal. just my memory left me for the week i was there. worst feeling ive ever experienced.
